A central problem in optical oceanography is to specify the submarine irradiance field as a function of depth and wavelength. For many applications, however, it is sufficient to know the average optical properties of a layer of arbitrary thickness. Among such properties is the diffuse extinction coefficient, which is strongly dependent on the local concentration of photosynthetic pigments. In general, vertical pigment profiles in the ocean can be represented by shifted gaussians that may be parameterized through field observations. We have found analytical results for the average extinction coefficients in arbitrary segments of such profiles. The results can be applied to the calculation of primary production through the evaluation of integrals of spectral irradiance weighted by the photosynthetic action spectrum.
